Versione 2.41 solved an old issue I had with TGAs with alpha!I'm very happy but I found a new bug. This is again a bug related to pictures with alpha but it happens with all formats with alpha. Not only TGA.This bug happen only when the picture is bigger then the screen. Xnview show the picture scaled so that it fits the screen and this cause the bug!If I zoom in or zoom out the picture, I see it perfectly.

I want to add another thing. This bug is visible only when Xnview's window is big as the screen (maximized)! If the Xnview's window is a floating window the bug disappears.

I show you the bug:

This is what I see when I double click a picture that has alpha and is scaled to fit the xnview canvas. Do you see all those white dots?

If now I zoom in or zoom out the the dots disappear. This image is at 100% here

If I open a picture smaller then the previous there is no bugs. In this picture I opened a scaled version of the previous image. See? No dots because it opens at 100% zoom

I add that the dots appear also if I click "M" to see the alpha of the picture. In this image the alpha is white. Do you see the black dots?

Mr Pierre!Another bug!!!!I hope you read this or I will have to open a new thread.

This new bug is related to the one I wrote in the first message!

Open the same picture of the first message. In my monitor the picture is initially shown at zoom 88%

Now press M to see the mask.Nothing happen! You don't see the mask!If now you zoom out you still don't see the mask!Now zoom in till you reach 100%! Tadaaaah! Now you see the mask! If you zoom out again the mask disappear again and you'll see the picture as normal.

In other words:The "show mask" feature only works when the picture is at 100% or more. If less you cannot see the alpha channel/mask

This bug is very annoying...not as the bug in the first post (the little white dots) that is not important.Bye!

When I open the png is shown at 88% to fit the window and it's a chaos of colours!If I zoom in to 100% or more it became white and grey (it's real colour)If I zoom out to less then 88% it became totally red (What???).

In order to turn View → Use alpha channel on and off, Ignore alpha channel (Tools → Options... → General → Operations) has to be disabled, and you have to open a 32-bit image in view mode. If you're dealing with a PNG file, you also have to deactivate → Compose image with alpha (32bits) in Tools → Options... → Read/Write → Read → PNG.
